Chinese Translation Software For Written Documents

Hi everyone, I am not sure if this is the appropriate forum for posting this question, but here goes...

Can anyone recommend a good Chinese to English translation software program for written documents? I use Google translate but I am tired of having to cut and paste so often and so much. I have to translate emails many times in a workday and I need to improve my efficiency somehow. I tried downloading a free version (can't remember the name), but it didn't install properly.

Specically, what I would like to able to do is take the text in an email or a Word document and highlight and click a mouse button and have it translated into English.
